4. Product Introduction
The Extreme Networks X460-G2-48p-10GE4 is a 48-port Gigabit PoE+ switch with four 10G SFP+ uplink ports. It serves both advanced edge and aggregation roles in enterprise and campus networks where high port density and Power over Ethernet are required.
Technicians who have deployed these in production stacks note reliable PoE delivery and solid ExtremeXOS stability when power supplies and cabling are correctly specified. The rear VIM slot allows further expansion for additional high-speed connectivity if needed.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power to switch | PSU failure or input issue | ✅ High | Verify AC/DC input and PSU status LEDs | Swap PSU or check power redundancy |
| PoE ports not delivering power | Budget limit or port config | ✅ High | Run “show inline-power” and “show power budget” | Reduce load or add second high-wattage PSU |
| SFP+ uplink no link | Wrong optic or speed setting | ✅ High | Run “show ports” and check transceiver | Use compatible 10G optics and set speed if needed |
| Stack not forming | Cable or software mismatch | ✅ Medium | Execute “show stack” command | Match firmware and verify stacking ports/cables |
| High fan noise or overheating | Airflow obstruction | ✅ Medium | Check intake/exhaust clearance | Ensure proper spacing and clean vents |
| Intermittent connectivity | MTU or QoS misconfiguration | ❌ Low | Review logs with “show log” | Adjust MTU and test with default settings |
